that to try to find them if we can't find them by absolute path.
This is intended to make everything still work if you copy an
entire directory tree of files that import each other.
Also add a mechanism to not paint the scene if we're not sure it's
consistent; otherwise got some crashes on startup. And disable both
text and graphic window when displaying a modal dialog, wasn't
doing that always.
[git-p4: depot-paths = "//depot/solvespace/": change = 1808]
to save our registry stuff (because we were calling exit() instead
of doing a PostQuitMessage()), and a misclassification of triangles
coplanar with the test surface, when the test surface contained
zero-area triangles.
[git-p4: depot-paths = "//depot/solvespace/": change = 1773]
using the initial numerical guess of whichever vector is already
known to choose our projection planes.
And add a mechanism to defer showing the text window or
regenerating, in order to simplify dependencies on valid actives.
Also yes/no/cancel when about to abandon an unsaved file, and a
bugfix when rotating a rot/trans point.
[git-p4: depot-paths = "//depot/solvespace/": change = 1772]
csg ops; so the union of a red part and a blue part has both red
and blue faces. And some user interface to pick the color in the
text window.
The metadata also include a face, which will be an entity; I can
use that to constrain against. But none of that is yet implemented.
[git-p4: depot-paths = "//depot/solvespace/": change = 1757]
recently opened files, that is saved in the registry and displayed
in a separate popup menu.
[git-p4: depot-paths = "//depot/solvespace/": change = 1752]
nicely. And to do that, I've added the user interface to show an
edit control in the text window.
[git-p4: depot-paths = "//depot/solvespace/": change = 1749]
and in the case of a singular Jacobian, report which constraints
can be removed to fix it. Also a mechanism to hover and select
entities and constraints from the text window.
[git-p4: depot-paths = "//depot/solvespace/": change = 1746]
the coordinate system (x, y, z normal vectors) in the bottom left
corner of the screen at all times, and hide group-created
workplanes except when that group is active, and activate that
workplane when the group is activated.
[git-p4: depot-paths = "//depot/solvespace/": change = 1726]
everything broke; apparently that driver didn't like me continually
destroying and recreating the HPGL context, and it also didn't like
me drawing zero-area polygons for my edges (which seemed like a
good idea, because it let me use glPolygonOffset instead of doing
that by hand). So it now all seems to work again, and faster.
[git-p4: depot-paths = "//depot/solvespace/": change = 1723]
segments), add the toggle construction command, and color the lines
differently depending on what group you're in.
Also change dynamic memory stuff to use a Win32 heap for everything
(no malloc), and validate that often. I think I've seen it crash,
though I can't reproduce it.
[git-p4: depot-paths = "//depot/solvespace/": change = 1708]
foreground and background colours are now specified separately, and
it's possible to insert half-line spaces. So now I have a window
that lets me show/hide groups, and select the active one.
[git-p4: depot-paths = "//depot/solvespace/": change = 1695]
erased before redraw, which caused a bit of flicker on show. And
hide debug prints in solver.
[git-p4: depot-paths = "//depot/solvespace/": change = 1693]
other entities. This requires a new point type, for a point that's
defined as a transformation of some other point. All works nicely,
I think. There's ugliness because entities are no longer guaranteed
to have a parent request.
Also speed up display of the text window, by caching brushes
instead of recreating for each character (!), and add a bit more
user interface in the text window.
[git-p4: depot-paths = "//depot/solvespace/": change = 1692]
workplane: a free constraint works in three-space (e.g. true
distance), and a constraint in a workplane works in that plane
(e.g. projected distance). And make the solver go automatically,
though solver itself has lots of pieces missing.
[git-p4: depot-paths = "//depot/solvespace/": change = 1691]
locked on to the XY plane. And simplify the handling of colors in
the text window: identify them by a character, not an integer ID,
since the character is easier to remember.
[git-p4: depot-paths = "//depot/solvespace/": change = 1687]
determine what goes in front (e.g. put a drawn line in front of the
reference plane, even if the z order would want the opposite), and
some tweaks to the mouse behaviour, and a function to modify
constraints like dimensions so that the are initially satisfied.
[git-p4: depot-paths = "//depot/solvespace/": change = 1681]
the label associated with a constraint. And that even works,
changes the length of the line.
[git-p4: depot-paths = "//depot/solvespace/": change = 1678]
and point-in-plane. These work, but the equation is still stupid,
solving everything at once and not substituting trivial equations.
[git-p4: depot-paths = "//depot/solvespace/": change = 1677]
stuff, though no file load stuff, and perhaps this can all be made
to work from a table somehow. Move the quaternion stuff into its
own class, and add a fancy animated view when you orient onto a
csys.
[git-p4: depot-paths = "//depot/solvespace/": change = 1672]
expressions that we wish to keep around. And make the 2d coordinate
system (that causes points to generate 2 unknowns, not 3) an
attribute of the request, not the group, and add user interface to
change that.
[git-p4: depot-paths = "//depot/solvespace/": change = 1670]
on-screen, and I can drag the label. That's progress. Also
implement a bunch of untested expression stuff, since I'll need
that for the values of the dimensions, for example.
[git-p4: depot-paths = "//depot/solvespace/": change = 1668]
the plane basis vectors) work, easy. Tweak the text window a bit,
for cosmetics, and start to add the symbolic expression code.
[git-p4: depot-paths = "//depot/solvespace/": change = 1667]
just for display, and any text entry will happen via some floating
text box, same as entering a dimension on the sketch.
Add the hover and selection mechanism, which now seems to work.
Still not clear how to do imported parts, for assemblies and
hierarchy. The handle formats may still have to change.
[git-p4: depot-paths = "//depot/solvespace/": change = 1662]
progress. I want to change the sketch.h stuff fairly significantly,
I think, before proceeding.
[git-p4: depot-paths = "//depot/solvespace/": change = 1657]
draw planes that I will use to do the datum planes. Still haven't
settled upon the request/entity/group structure, and that's the
dependency before doing much real.
[git-p4: depot-paths = "//depot/solvespace/": change = 1656]
the text window every time we refresh the graphics window, because
that's slow. Use classes instead of structs for everything; I don't
understand the template handling for structs. And implement the
IdList, which I will try to use in many places.
[git-p4: depot-paths = "//depot/solvespace/": change = 1655]
and add some (non-functional) menus to the graphics window. Start
to rough in some data structures to hold the sketch. No real work
yet, though.
[git-p4: depot-paths = "//depot/solvespace/": change = 1653]
constraint solver drawing. I've started work on the user inteface,
which will be based around two windows: one with the graphical
sketch, and one command line. I've started to implement the command
line, no other work.
